Biotechnology

Biotechnology is using micro-organisms in the production of food, medicine and materials.

These micro-organisms can be

  • Bacteria - uni-cellular
  • Fungi     - multi-cellular

Favoured Conditions for Growth

  • Warm - 35-39*C because it's the optimum temperature for enzyme activty
  • Moist - to prevent dehydration which allows growth, therefore more successful effective reactions
  • Oxygen - to allow aerobic respiration
  • Food source - respiritary substrate
